Dyson V15 Detect: Saturn's low-cost laser cordless vacuum cleaner

March 8, in the three sessions of the 14th National People's Congress, the second “representative channel” focused on interviews, the National People's Congress, the party secretary of HGTECH Science and Technology, Chairman of the Board of Directors Ma Xinqiang, said in response to a reporter's question, in order to crack the “strangle  “technical problems, HGTECH over the years in the field of h...

The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...

German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
